Salsolinol: an Unintelligible and Double-Faced Molecule—Lessons Learned from In Vivo and In Vitro Experiments [PDF]
Salsolinol (1-methyl-6,7-dihydroxy-1,2,3,4-tetrahydroisoquinoline) is a tetrahydroisoquinoline derivative whose presence in humans was first detected in the urine of Parkinsonian patients on l-DOPA (l-dihydroxyphenylalanine) medication.

The ubiquitin‐specific protease 7 (USP7) catalyzes the removal of ubiquitin and protects substrate proteins from degradation. USP7 causes structural changes upon ubiquitin binding, making it particularly suitable for use in covalent targeting approaches. The development, synthesis, and biophysical screening of a series of mildly electrophilic compounds

Advances in Ligand‐Driven Pd‐Catalyzed C─H Functionalizations: Recent Insights and Updates
The most significant advances in ligand‐driven Pd‐catalyzed organic synthesis over the past two years are presented. Processes involving C─H activation of substrates, avoiding their prefunctionalization are illustrated. Both the activity and selectivity of the catalyst depend on the design of the ligands (pyridones, pyridines, amino acids, phosphines ...

Plant‐derived compounds such as polyphenols, flavonoids, alkaloids, and terpenoids exhibit neuroprotective, antioxidant, and anti‐inflammatory activities in Parkinson's disease models. Unlike levodopa, they provide disease‐modifying benefits by targeting α‐synuclein aggregation, mitochondrial dysfunction, and neuroinflammation.
